Automobile side body outer plate mould with double-layer sliding block structure

Abstract

The invention provides an automobile side body outer plate mould with a double-layer sliding block structure. The automobile side body outer plate mould comprises a double-layer sliding block structure. The double-layer sliding block structure slides in a lower mould seat according to different directions, side flanging is completed through working of the double-layer sliding block structure and flanging embedded parts on an up-down movement sliding block during working, and the double-layer sliding block structure includes a sliding block and a secondary sliding block. The sliding block is arranged in the lower mould seat and fixed to the lower mould seat by relying on a pressing plate, and a side sliding plate installed on the side face is matched with a sliding guide face on the lower mould seat for sliding guide. The secondary sliding block is installed in front of the sliding block and does movement in the sliding block by relying on the pressing plate, a sliding plate and the side sliding plate. According to the automobile side body outer plate mould with the double-layer sliding block structure, the structure with the double-side sliding blocks and a material pressing plate which is provided with the slides is adopted, elusion of side body outer plate avoiding angles is achieved, and forming of side flanging on the same mould is completed; the development cost of the mould is lowered by the structure, 2,600,000 yuan is totally reduced for the development cost of the left and right side body outer plate mould, the occupied area of the stamping workshop area is saved, working efficiency is improved, and the accuracy requirement for automobile assembling is met.

Description

technical field [0001] The invention relates to the technical field of mold design, in particular to an automobile side wall outer panel mold with a double-layer slider structure. Background technique [0002] The structure of the side outer panel parts is complex, and the manufacturing process needs to go through stretching, forward and side trimming, punching, up and down flanging and shaping. According to the design principles of professional mold factories, blanking, stretching, forward trimming and punching, up and down flanging and shaping, and side punching and trimming are required to complete the five steps. Both the upper and lower molds of the used upper and lower flanging molds have live cores. Due to the asymmetry of the upper and lower flanges, the live cores are subjected to large lateral forces, which reduces the life of the mold. In the actual working state of the mold, due to the unreliable performance of the elastic elements, the sequence of the upper and...

AI Technical Summary

Problems solved by technology

[0004] (1) The cost of the side wall outer panel stamping die is high. Calculated based on the side wall outer panel of a general medium-sized car, the mold size is 3500mmx2100 mmx1200 mm, and the mass is 26140 kg. The research and development cost is 2.6 million yuan, and the development cost of mold tooling is very high

[0005] (2) The size of the mold is large, which occupies a large storage space in the stamping workshop and increases the maintenance cost of the workshop

[0006] (3) During the production process, the mold needs to be replaced and adjusted, and the production efficiency is low

[0009] Since the punching die repair requires the lower die to remain still, the upper die to move downward, and the upward flanging die requires the lower die to move upward, the existing equipment can only provide one-way movement, so there are many processes and corresponding molds
